If a 25 in by 32 in picture has a wooden frame x in wide surrounding it which equation can be used to find the total area of the picture and frame?

The frame is at each side of the picture so the area is (25 + 2x) times (32 + 2x), (which multiplies out to 4x^2 + 114x + 800 square inches). ie if the frame is an inch and a half wide then the area is 28 x 35 sq ins, ie 980 sq ins.
